The plant transplanting technique from natural regeneration in areas under reforestation is considered of great importance not only for constituting the necessary diversity in a forest restoration program, but also, due to the possibility of conserving genetic material that would otherwise be deleted. The objective of the research was to know in which seasons and in which height classes higher levels of survival and initial growth of plants rescued from Vernonia discolor, Myrsine coriacea and Vernonanthura discolor, under development in the Eucalyptus reforestation understory, can be obtained. Quarterly collections of 36 seedlings of each species were carried out, 12 of each of the following classes of heights: 5 to 25 cm; 26 to 49 cm; and ≥ 50 cm. On the occasions when the seedlings were rescued, measurements were taken of the total height, the stem diameter, the canopy length and the canopy diameter. After the rescue, the seedlings were transplanted and kept in a nursery for 90 days, with the same variables being measured at the end of this period. All species studied showed greater survival and increases in height and diameter of the collar, when rescued up to 50 cm in height. The three species showed a low relationship between increments in height and diameter of the collection with the climatic seasonality of the seasons. [ABSTRACT FROM AUTHOR]
